Personally the D5200 is much better, it's a little bit cheaper also. 39 vs 11AF points and a couple more megapixels, same high ISO performance and both have great quality and medium sized bodies. You won't go wrong with any of these obviously, but since the D5200 is cheaper and same or better at most aspects, I'd recommend you to go with it.
